Kupu Whakataki:
Ngā pākahiko lithiumkua noho hei wāhanga nui o tō tātou oranga o ia rā, e whakakaha ana i ngā mea katoa mai i ngā waea atamai me ngā pona ki ngā waka hiko me ngā pūnaha rokiroki pūngao hou. He haerenga whakamīharo te hītori o ngā pākahiko lithium e mau ana i ngā tekau tau, e tohuhia ana e ngā whanaketanga nui o te hangarau me te auahatanga. Mai i ngā tīmatanga iti ki tō rātou tūranga o nāianei hei otinga rokiroki pūngao matua, kua hurihia e ngā pākahiko lithium te huarahi e whakamahia ai e tātou me te penapena hiko.
Te hanganga o ngā pākahiko lithium
Te kōrero mōngā pākahiko lithiumi tīmata i te tekau tau atu i 1970, i te wā i tīmata ai ngā kairangahau ki te tūhura i te pūmanawa o te lithium hei wāhanga matua o ngā pākahiko ka taea te whakahou. I tēnei wā ka kitea e ngā kaipūtaiao ngā āhuatanga ahurei o te lithium, tae atu ki tōna kaha nui me tōna māmā, ā, he mea tino pai mō ngā taputapu hiko kawe. Nā tēnei kitenga i whakatakoto te turanga mō te whanaketanga o ngā pākahiko lithium-ion, ka noho tonu hei rangatira i te mākete hiko kaihoko mō ngā tau e haere ake nei.
I te tau 1979, i puta he putanga hou mai i te matū o Te Whare Wānanga o Oxford, a John Goodenough, me tana tīma, ā, i whakawhanakehia e rātou te pākahiko lithium-ion tuatahi hei utu anō. Nā tēnei mahi matua i whakatakoto te turanga mō te hokohoko o ngā pākahiko lithium-ion, e tere haere ana te rongonui nā te mea he pai ake te mahi me te roa o te ora ratonga ki te whakataurite ki ngā pākahiko waikawa-mata me te nickel-cadmium tuku iho.
I ngā tau 1980 me 1990, he nui ngā mahi rangahau me te whanaketanga i arotahi ki te whakapai ake i te mahi me te haumaru o ngā pākahiko lithium. Ko tētahi o ngā wero matua ko te kimi i tētahi electrolyte pumau e taea ai te tu atu i te kaha nui o te lithium me te kore e whakararu i te haumaru. Nā tēnei i hua ake ai te whanaketanga o ngā momo hanganga electrolyte me ngā pūnaha whakahaere pākahiko e whakapai ake ana i te pono me te haumaru o ngā pākahiko lithium-ion.

Ko tētahi o ngā wero matua ko te kimi i tētahi electrolyte pumau e taea ai te tu atu i te kaha nui o te lithium me te kore e whakararu i te haumaru. Nā tēnei i hua ake ai te whanaketanga o ngā momo hanganga electrolyte me ngā pūnaha whakahaere pākahiko e whakapai ake ana i te pono me te haumaru o ngā pākahiko lithium-ion.
Ko ngā tau tōmua o te tekau tau atu i 2000 te wā i huri ai ngā pākahiko lithium, me ngā whanaketanga o te nanotechnology me te pūtaiao rauemi i akiaki i te whanaketanga o ngā pākahiko lithium rino phosphate (LiFePO4) me ngā pākahiko lithium polymer. Ko ēnei matū pākahiko hou e tuku ana i te kiato pūngao teitei ake, ngā āheinga utu tere ake me ngā āhuatanga haumaru whakarei ake, e whakawhānui ake ana i te whakamahinga o ngā pākahiko lithium i roto i ngā rāngai motuka, rererangi me te pūngao whakahou.
Te heke mai o ngā pākahiko lithium
Ko te whānui o te whakamahinga o ngā waka hiko (EV) me te pikinga o te hiahia mō ngā otinga rokiroki pūngao kua akiaki i te whanaketanga o ngā waka hiko mahi-teitei.ngā pākahiko lithiumI ngā tau tata nei, nā ngā whanaketanga nui o te hangarau pākahiko pērā i ngā irahiko totoka me ngā anode silicon kua whakapai ake i te kiato pūngao me te roa o te huringa o ngā pākahiko lithium, ā, he kōwhiringa pai mō te rokiroki pūngao nui me te pumau o te whatunga hiko.
Ko te hītori o ngā pākahiko lithium e whakaatu ana i te whai tonu i te auahatanga me te mana whakarerekē o te hangarau. I ēnei rā, ko ngā pākahiko lithium te tūāpapa o te whakawhiti pūngao ma, e āhei ai te whakamahi whānui i ngā waka hiko me te whakauru i te pūngao whakahou. I a te ao e rapu ana ki te whakaiti i tōna whakawhirinaki ki ngā wahie pūmua me te whawhai ki te huringa āhuarangi, ka whai wāhi nui ngā pākahiko lithium ki te hanga i tētahi heke mai pumau me te iti-waro.
Whakamutunga
Hei whakarāpopototanga, ko te hītori whanaketanga ongā pākahiko lithiumHe haerenga whakamiharo tēnei o te kitenga pūtaiao, te auahatanga hangarau, me te panonitanga ahumahi. Mai i ōna rā tuatahi hei taonga taiwhanga ki tōna tūnga o nāianei hei otinga rokiroki pūngao whānui, kua roa te huarahi kua haere mai ngā pākahiko lithium ki te whakakaha i te ao hou. I a tātou e haere tonu ana ki te whakatuwhera i te pūmanawa katoa o ngā pākahiko lithium, ka whakatūwherahia e tātou he wā hou o te rokiroki pūngao ma, pono me te pumau ka hanga i te heke mai o tō tātou ao.
